Trey and his friends are walking home when they get caught in a thunderstorm. they decide to find shelter to get away from the rain and lightning. after looking around, they see two places they can go: a wooden gazebo or an aluminum shed. trey has studied physical science and tells his friends they should stand under the wooden gazebo. which best describes why trey and his friends should go to the gazebo to be safe from the thunderstorm? a. if enough rain falls on the shed, the aluminum's property of tarnishing easily could cause the shed's door to be sealed shut. b. if lightning strikes the shed, the aluminum's property of fracturing easily under pressure could cause the shed to collapse. c. if lightning strikes the shed, the aluminum's free-floating electrons could easily conduct the electricity throughout the shed. d. if enough rain falls on the shed, the aluminum's free-floating electrons will lose their charge and attract lightning to strike the shed.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
